I don't have evidence of it, but I get the feeling MQ and Baylee were not there that night. I could see MQ putting out a hit for James if he was stirring up trouble with the business and to basically quiet him. The suggestion someone had upthread that James could have been buying guns for the group was intriguing. It could explain why the chiropractor might owe him money. Nothing else seems to make sense to me as to why SB would owe James money.
The fact that there was search warrants for some of these people and it seems LE must have had some idea of activities and how quiet LE has been about these three makes me wonder if they have an inside person. Could they be trying to gather enough evidence to not just convict on murder, but also for all of the other illegal activity? Otherwise, I just don't understand how there could be no arrests for James' murder at the very least.
